Title: Method for assigning frequency allocation of base station in a mobile communication
Inventor: CHO GYEONG RAE
IPC: H04W16/00
Filed: 2002-12-24
Abstract: PURPOSE: A method for allocating frequency resource of a base station in a mobile communication system is provided to calculate the smallest number of frequency resources by controlling frequency resources of each base station required for providing service with the same quality. CONSTITUTION: A total amount(T) of requested traffic of a certain service area is calculated(200). A total number(Bn) of base stations of the certain service area a base station radio capacity(B1) for 1FA are inputted(205). The number of the first frequency resources is calculated(210). An initial value of the number(Bn1) of the first base stations is set to be the same as the total number of base stations(Bn)(215). An amount of residual traffic is calculated(225). It is determined whether the amount of residual traffic is smaller than 0(230). If the amount of residual traffic is not smaller than 0, the second frequency resource is calculated(235). It is determined whether the number of the first frequency resources and the number of the second frequency resources are the same(240). If they are the same, it is determined whether the number of the first base stations is equal to a value obtained by subtracting 1 from the total number of base stations(245). If the number of the first base stations is equal to a value obtained by subtracting 1 from the total number of base stations, the number of the second base stations is 1 and FA of every base station is determined with the first frequency resource(260).

Abstract: PURPOSE: A method for controlling a menu or recent call list by using a hiding function in a wireless communication terminal is provided to realize a simpler menu by setting a hiding mode to a menu which is not frequently used. CONSTITUTION: A mobile communication terminal receives a hiding function key in a state that a cursor is placed at a random menu(201). A hiding mode setup confirmation message is output to an LCD(Liquid Crystal Display)(202). If a confirmation key is inputted, a hiding mode is set up to the menu(204). If a cancel key is inputted, contents of the LCD are restored to a state before the hiding mode setup confirmation message is output(205). If receiving a menu display key, the mobile communication terminal displays menus except the menus to which the hiding mode is set up(206).
